The challenge: Raspberry disease within propagation and in production can be devastating for growers, and can lead to devastating losses, with raspberry root rot causing losses of up to 20% in UK production. Raspberry root rot is often diagnosed as Phytophthora rubi, which is known to be the main causing agent of root rot in raspberries in the UK. However, adequate early disease detection methods are not available, meaning early detection of this disease is not often possible.
The study: FungiAlert worked with three leading raspberry growers in the UK to understand if FungiAlert’s SporSenZ screen could be used to detect disease pressures in raspberry growing systems. The identification of disease risks would ultimately allow for timely remedial action to be taken, and would improve disease management strategies to mitigate disease losses.
✔ Although raspberry root rot is mainly diagnosed as Phytophthora rubi, the SporSenZ screen identified a number of different raspberry pathogens known to cause raspberry root rot.
✔Raspberry tissue samples from diseased shoots and roots were also analysed, again highlighting the importance of other raspberry pathogens in causing root rot.
✔ A number of post harvest fruit rot pathogens were also detected during the growing season.
✔ FungiAlert’s SporSenZ screen results uncovered a number of causing agents of raspberry root rot, not just Phytophthora sp.
✔ FungiAlert’s plant tissue analysis services also highlighted the importance that other pathogens play in causing raspberry root rot in raspberries.
✔ The SporSenZ screen highlighted post-harvest fruit rots early in the raspberry season, giving the growers an early alert to potential post harvest diseases, and allowing remedial action to be taken in time.
